DEVICE FOR GUIDING AND STRIPPING- THREAD 0N WINDIN 'G-FRAMES.

Specification of Letters Patent.

Application filed September 15, 1909.

Patented Apr. 11, 1911.

Serial No. 517,762.

sist essentially of a plate which has a slit formed in it to receive the thread, and these guides have the defect that the fiuif which becomes entangled with the thread in the spinning operation, forming little lumps or knots in the thread, is not removed in pass ing through the slit but simply compressed, and the thread emerges from the slit with the lumps or knots flattened.

My invention obviates this defect.

In the accompanying drawing: Figure 1 shows diagrammatically the arrangement of thread guide A, in side elevation, and Figs. 2 to 4 show respectively a plan View, an end view and a side elevation of the said thread guide on a larger scale.

Referring to the drawings: The thread guide A consists of two parts, viz: a spindle a which has a downwardly extending flattened extension I) that is secured by means of two bolts to a suitable part of the winding frame, and a pivotally mounted bracket arm 0. The arm 0 is stamped out of sheet metal and has at its rear end two lugs 65 bored to receive the spindle a. In order to reduce to a minimum the friction caused by the pressure of the arm 0 against the shoulder of the spindle a, a glass ring 6 is introduced between the arm and the shoulder. This shoulder is in the form of an adjustable collar T which can be set higher or lower to regulate the vertical position of the complete thread guide.

The thread guide proper, consists of a plate 9 which serves both as a guide and a cleaner or stripper; it is formed with a lug h and mounted on the arm 0 by means of a screw 7'. The lug it has a longitudinal slot formed in it to enable not only the angle at which the plate is setwhich as a rule is about 35 to the horizontalto be-varied, but also the height of the plate relatively to the path of the thread to be regulated. The thread C passes over the guide roller 2', which is mounted on the arm 0, and then through the slit k and over the guide Z to the bobbin D." As the arm 0 is pivotally mounted it adjusts itself automatically to suit the direction in which the thread is moving, and consequently there is no sharp bending of the thread as it leaves the slit 7c. Knots of fiulf or the like in the thread cannot pass through the slit 7c. Owing to the inclination of the plate 9 such knots are guided down to the bottom of the slit, where they are impaled on the point of a needle m mounted on'the underside of the plate g.

What-I claim as my invention and desire to secure by Letters Patent is:

1. A thread guide for winding frames comprising a bracket arm rotatably mounted on a vertical spindle, a plate fixed on the said arm inclined at an angle to the axis of the said spindle and formed with a slit to guide the thread, and a knot-stripping needle mounted on the said plate at the lower end of the said slit.

2. A thread guide for winding frames comprising an arm rotatably mounted on a vertical axis, a plate formed with a slit to guide the thread and a slot to adapt the said plate to be secured adjustably, by means of a screw, upon the said arm at a variable height relatively to the said arm and at a variable inclination to the said vertical axis, and a knot-stripping needle mounted on the underside of the said plate at the lower end of the said slit.
